Both of the AA kits are all resin now (with a PE fret), the white metal bits are in the older original kits but Derek can sort you out with resin replacement parts. IIRC the only difference between the two is the cupola on the Mk-I and the peak turret on the Mk-II, aside from that the kits should be identical.
I built the Mk-I for the August issue of MMI, it's a fairly straight forward kit without a ton of parts.
